To give you guys an idea of the size of that number , there are approximately 3000000000000000000000000 stars in the known universe . Three followed by twenty four zeroes , which is a smaller number than the dilution of this delusion !

Homeopathy is given credit when in fact people would be cured with or without it. People will give credit to all sorts of false causes. So at best it is a placebo when it 'works' for mild illnesses and it is dangerous when it doesn't for serious illnesses. Homeopathy is just one big logical fallacy, it's the classic post-hoc fallacy.

Here are three excerpts taken from an article by Ben Goldacre - the guardian newspaper

Here is a model trial for homeopathy. You take, say, 200 people, and divide them at random into two groups of 100. All of the patients visit their homeopath, they all get a homeopathic prescription at the end (because homeopaths love to prescribe pills even more than doctors) for whatever it is that the homeopath wants to prescribe, and all the patients take their prescription to the homeopathic pharmacy. Every patient can be prescribed something completely different, an "individualised" prescription - it doesn't matter.
With alternative therapists, when you point out a problem with the evidence, people don't engage with you about it, or read and reference your work. They get into a huff. They refuse to answer calls or email queries. They wave their hands and mutter sciencey words such as "quantum" and "nano". They accuse you of being a paid plant from some big pharma conspiracy. They threaten to sue you. They shout, "What about thalidomide, science boy?", they cry, they call you names, they hold lectures at their trade fairs about how you are a dangerous doctor, they contact and harass your employer, they try to dig up dirt from your personal life, or they actually threaten you with violence (this has all happened to me, and I'm compiling a great collection of stories for a nice documentary, so do keep it coming)
American magician and debunker James Randi has for many years had a $1m prize on offer for anyone who can demonstrate paranormal abilities. He has made it clear that this cheque would go to someone who can reliably distinguish a homeopathic dilution from water. His money remains unclaimed.
